Maybe the first ones that had the problems(per David Lennard- F-20c sailor) had twist and that was the problem. Mike Krantz said they had twist per post #243870 a couple pages back, and he's had to see a few. So maybe it's quality control instead of engineering genius.

For the F20c, there is a definite "twist" to the boards. It's not a straight curve...
